According to this review on Musicians Friend, looks like it will do the 4 cable method.
Looks really cool but very expensive @ $685,
but I do Love my Plexitone
Comments about Carl Martin Quattro Analog Multi-Effect Pedal:
Wow! This thing blew away all my other stomp boxes in terms of quality and sound.
As soon as I hooked this up with the 4 cable method to have the chorus and delay in the loop I knew it was a winner. My tone has improved leaps and bounds.
I think with the 12V power and not running a bunch of patch cables this unit has improved my rig overall even when I'm not using its effects.
I have been through more effects than I can count, digital and analog. Singles boxes and multi FX units.
This is the one if you are into great non digital tone. Well worth the $$
